and in Austria May 19, 1931 Claims. (Cl. 254-135) This invention relatesto a device for the mounting and anchoring of transportable hoisting andhauling appliances, and has for its principle to mount an appliance ofthe said order in such a manner as to be rotatable between a standingstirrup-shaped member and a ground support placed at. right angles tothe direction of pull, the said support together with a further groundsupport. disposed parallel to the direction of pull being adaptedthrough the use of means to be described hereafter to be secured to theground in such a manner that the same is firmly anchoredwith respect tothe direction of pull, but at the same time is easily detachable fromthe ground.

The requirements of such a device as the present invention sets out toprovide, particularly for use in connection with hand winches orcapstans for the lifting or salving of vehicles and for thehauling ofthe same over obstacles and steep places, or the like, are in the firstplace that it shall enable the lifting and hauling devices attachedthereto to-be. adjusted and set in Y position with their axes ofrotation in the desired relation to the direction of pull, and in thesecond place that it shall be able to anchor the said appliances in-anynatural or artificial ground conditions so effectually and reliably thatthe load can be hauled or lifted without danger of slipping or givingway. A further essential requirement is that, with a view to reducingthe dead Weight of the vehicle, the device must be light in weight andmust be capable of being fixed in position and operated by one man (thedriver of the vehicle alone).

The' problem here presented has been solved by the present invention,since the device provided therebyis of extremely light Weight, en-

. ables areliable anchorage to beobtained in a sake of simplicity merelyindicated in the draw-.

' ing as a drum T which is to be taken as representing either a Windlassdrum, a capstan drum,

or the efiective drum of a whole set of drums or rollers, since theparticular arrangement and construction'of the lifting or haulingappliance itself is immaterial to the present invention. The supportingof the lifting or hauling appliance I is eifected by a ground support 1disposed at right angles to the direction of pull, on which support theaxle 2 of the lifting or hauling appliance T is articulated so asv to betiltable about a bolt 3, while the upperendof the axle 2 is fitted in astirrup-shaped member 4 which, is likewise tiltably mounted on theground support'll by i means of bearing lugs 1' to which the'stirrup 4;

is attached for instance by means ofbolts and 7 nuts. In the middle ofthe ground support 1 there is provided a hinge joint 5 by'means 'ofwhich a further ground support fi disposed inv the direction of pull canbe articulated to the transverse supporting member 1. 'Ihe;longitu-.dinal support 6 is provided at its rear end with a coupling member '7,in' the form ofa shackle, eye, or .the like, byme'ansof which additionalextension supports 6 of the'same type as 6 can be connected ascircumstances require. The pivoted stirrup 4 isprovidediin its upperpart with a hinge 8to which'a backstay or support. 9

is articulated for the purposeof enabli'ngthe angular adjustment oftheaxle 2 of the drum T in relation to the ground support. l tojbejfixed. In order to obtain a reliable fixation ortne back stay Qfin'.view of the very"'great pulling'strains to be dealt with, a clampingeccentriclever 10 is slidably attached to the longitudinal supportingmember 6. To this end' the clampinglever 'm is held to the supportGby'YmeansOf a band or stirrup ll-and an adjusting screw 13 passedthrough the ends of this, stirrup and through the eccentric pivothole inthe foot portion of the said lever. The slackening of the screw 13enables the lever 10 to be slid longitudinally of the support 6. As willbe clear from the drawing, this construction causes the lever 10 tobemore firmly clamped to theflsupport 6 the greater is the pull exertedonthe drum T, thus precluding the alteration of the setting of. the backstay 9 through slip, irrespective of. the weight of the load; In orderto further facilitate the adjust,

ment of the angle of the drum axis, the back The anchoring of thesupporting members 1 and 6 in the ground is effected by means of specialpeg shoes or lugs which are either rigidly connected to the supports(formed. simultanestay 9 is provided with a plurality of holes 9' towhich the clamping lever 10 can be attached as required, for instance bymeans of a bolt or bolts "passed through both parts.

ously therewith by swaging) or are arranged to be slidably adjustablethereon. In the example shown in the drawing, the support 1 has a pegshoe 14 of this type at each end, these shoes being provided with a hole15 inclined at an angle to the vertical. Through these holes pegs P(nails, pins, bars, or the like) are either inserted or driven by meansofa hammer or other suitable tool into the ground. The support 6 islikewise provided with similar lugs 16 which are also obliquely drilledto receive the described anchoring members P driven therethrough intothe ground.

For the purpose of anchoring the supports into a street surface formedof blocks, a modified form of support 6a, as shown in Fig. 2, isemployed on which the peg lugs16a are adapted to be slidable in an axialdirection and to be clamped in position by means of screws 18. Theselugs are provided with vertical holes through" which the pegs P can bedriven into the crevices between'the blocks, thesepegs being held inposition in the holes of the lugs 1611 by means of set screws 19. 7

By' means of these special anchoring elements it becomes possible toanchor the hoisting or hauling appliance to any kind of ground met withunder practical conditions. In the case of soft humus or marshy groundit'merely be comes necessary to link together as manylongitudinal'supporting members 6, 6, etc. as possible with-a view toenabling as large a number of pegs as possible to be employed. Thesepegs? can bedriven by hand, and, in view of their oblique and cross-wisepositions, grasp as large as possible a volume of the ground material,and thusprovide a reliable anchoring of the hoisting or haulingappliance even for the heaviest loads. In'the case of hard ground asingle longitudinal support 6 is sufiicient, the lugs 16 being anchoredby means of pegs driven into the ground byhand, while in the case ofroad surfaces formed of stone or other blocks the method of anchoringillustrated in Fig. 2 is adopted, whereby the lugs can be adjustedlongitudinally oi? the support to en-' able the pegs to be drivenvertically into the crevices between the blocks. The adjustment of theangular position of the hoisting or hauling device is effectedby theadjustment of the back stay 9 or of the clamping lever 10, after firsttilt ing the stirrup l 'and therewith the drum T into the requiredposition. Since the foundation for the device according to the inventionis resolvable essentially into two bars (of round, T-shaped, or othercross-section) {the deviceis of light weight, easily manipulated, andyet capable of providing a reliable anchorage for a pulling strain ofany magnitude.
